“The Awei Q9s are really bang for bucks! You can't go wrong with these! Unless you have tiny ears...
Packaging: the packaging is standard. It brings the S/M/L tips and a shirt-clip. However, the earbuds are snugged in a very good foamy protective material.

Disclaimer
I bought these about 3 years ago, used them a lot and got to "know" them well. The (sort of a) good thing is: They still perform as good as they did when I first tried them on.
